Kev txhaj tshuaj molding yog ib txoj kev los tsim cov khoom sivkev tsim cov khoom hollowlos ntawm kev siv roj siab los tshuab thiab o cov qe kub yaj kaw rau hauv pwm. Lub tshuab hollow blow molding yog extrude los ntawm lub extruder thiab muab cov thermoplastic tubular blank uas tseem nyob hauv lub xeev softening rau hauv pwm molding. Tom qab ntawd los ntawm cov cua compressed, siv lub siab cua los deform lub blank raws lub qhov tuag, yog li ntawd tshuab mus rau hauv lub caj dab luv luv hollow khoom.
Hollow blow molding yog qhov tseem ceeb tshaj plaws rau kev tsim cov khoom yas hollow.Yuav luag txhua yam thermoplastics siv tau rau hollow blow molding, xws li polyethylene, PVC, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate thiab poly acid formaldehyde resin, thiab lwm yam.
Nrog rau cov txheej txheem molding no, nws tsis tsuas yog ua tautsim khoom me me ntimcov fwj ntau milliliters tab sis kuj tuaj yeem ua tautsim khoomntau txhiab litres ntawmloj heevcov thoob dej thiab cov thoob dej cia khoom, nrog rau cov pob ntab, cov thoob roj tsheb thiab cov kayaks.
Cov khoom siv tshuab molding yuav tsum muaj cov yam ntxwv dab tsi?
1.Kev tiv thaiv kev tawg ntawm ib puag ncig: ua ib lub thawv, nws muaj peev xwm tiv thaiv kev tawg thaum nws los rau hauv kev sib cuag nrog surfactant;
2.Huab cua nruj (kev tiv thaiv permeability): hais txog cov yam ntxwv uas tiv thaiv kev sib kis ntawm cov pa oxygen, carbon dioxide, nitrogen thiab cov pa dej.
3.Kev tiv thaiv kev poob siab: txhawm rau tiv thaiv cov khoom hauv lub thawv, cov khoom yuav tsum muaj kev tiv thaiv kev cuam tshuam uas tsis tuaj yeem tawg los ntawm ib 'meter' qhov siab.
4. Tsis tas li ntawd xwb, muaj kev tiv thaiv tshuaj, kev tiv thaiv zoo li qub, kev tawv thiab kev tiv thaiv extrusion.
Cov txiaj ntsig ntawm kev siv tshuab molding yog dab tsi?
1. Cov qauv khoob, ob chav phab ntsa tuaj yeem nqus thiab tshem tawm lub zog cuam tshuam;
2. Tsim qauv yooj yim, nrog kev ua haujlwm siab thiab tus nqi tsim khoom tsawg;
3. Cov txheej txheem ua tiav tuaj yeem hloov qhov tuab ntawm lub embryo;
4. Thaum lub sijhawm ua tiav, qhov tuab ntawm cov khoom tuaj yeem hloov pauv ntawm qhov xav tau yam tsis muaj kev txhim kho ntawm cov pwm;
5. Kev txhaj tshuaj pwm siab tsawg (kev ntxhov siab sab hauv ntawm pwm me dua li ntawm kev txhaj tshuaj molding), yog li txhim kho kev ruaj khov ntawm qhov ntev, kev tiv thaiv tshuaj lom neeg thiab kev ua haujlwm kub siab;
6. Kev sib dhos sib txawv: tus kheej tapping ntsia hlau, tuag ntxig, rivet nthuav dav fastener;
7. Pwm yooj yim, pheej yig thiab ua haujlwm luv luv;
8. Cov pwm qauv nrog tus nqi qis tuaj yeem tsim tau sai.
Tshuab pwm yog ib txoj kev tsim khoom uas siv cov khoom yas khoob los ua: Nws kuj siv rau kev tsim cov fwj iav. Feem ntau, muaj peb hom tshuab pwm tseem ceeb:kev txhaj tshuaj molding, extrusion molding, thiab kev txhaj tshuaj stretch molding.

.Kev nyab xeeb siabnrog kev ruaj ntseg tsis siv neeg xauv khoom siv hauv txhua qhov kev ua haujlwm kho tshuab, uas yuav ua rau cov txheej txheem tig mus rau hauv lub xeev kev nyab xeeb yog tias muaj kev tawg hauv qee txoj kev ua haujlwm.
Yeej yogtshuab pwmyog ib qho kev ua cov khoom yas khoob thiab ua lub thawv sib txuas cov khoom no. Nws muaj ntau yam duab thiab qhov ntau thiab tsawg. Tshuab moulding thiab txhaj tshuaj molding yog ib qho ntawm cov txheej txheem siv ntau thiab feem ntau siv nrog cov txheej txheem no pebtsim khoom cov khoom yas zoo hauv tus nqi qis tshaj plawsyog li qhov no yog txoj hauv kev zoo uas siv nyiaj tsawg. Tshuab pwm yog ib txoj kev siv qub los tsim cov khoom khoob. Hauv Tshuab pwm ntau yam muaj feem cuam tshuam xws li "hom yas, qhov ceev, qhov ceev, qhov kub.Cua yog ib qho tseem ceeb thiab ua lub luag haujlwm tseem ceeb hauv kev tshuab pwm. Cua raug thawb rau hauv pwm kom nthuav dav thiab muab nws cov duab xav tau. Cov txheej txheem tshuab pwm yooj yim heev, siv tau zoo heev thiab suav nrog cov tshuab pheej yig, kev tsim cov fwj yas siv cov txheej txheem no pheej yig dua piv rau kev txhaj tshuaj pwm. Hauv kev tshuab pwm, pwm tsis tas yuav tsum tau ua rau pwm raug siab.
Tshuab moulding - yog ib qho txheej txheem tsim khoom tshwj xeeb heev uas cov khoom yas hollow raug tsim thiab tuaj yeem sib koom ua ke.
Ibtshuab pwmsiv dav hauv kev tsim dej haus lag luam. Lub tshuab pwm tsim lub raj mis yas raws li daim ntawv qhia ua noj, piv txwv li qhia qhov peev xwm ntawm lub raj mis uas yuav tsum tau ua. Lub tshuab muaj cov pwm, lub tshuab tswj kev siv logic, thiab cov cuab yeej siv tshuab thiab hluav taws xob.
